RÉSUMÉ
Children with cancer often endure a range of psychoneurological symptoms (PNS), including pain, fatigue, cognitive impairment, anxiety, depressive symptoms, and sleep disturbance. Despite their prevalence, the underlying pathophysiology of PNS remains unclear. Hypotheses suggest an interplay between the gut microbiome and the functional metabolome, given the immune, neurological, and inflammatory influences these processes exert. This mini-review aims to provide a synopsis of the literature that examines the relationship between microbiome-metabolome pathways and PNS in children with cancer, drawing insights from the adult population when applicable. While there is limited microbiome research in the pediatric population, promising results in adult cancer patients include an association between lower microbial diversity and compositional changes, including decreased abundance of the beneficial microbes Fusicatenibacter, Ruminococcus, and Odoribacter, and more PNS. In pediatric patients, associations between peptide, tryptophan, carnitine shuttle, and gut microbial metabolism pathways and PNS outcomes were found. Utilizing multi-omics methods that combine microbiome and metabolome analyses provide insights into the functional capacity of microbiomes and their associated microbial metabolites. In children with cancer receiving chemotherapy, increased abundances of Intestinibacter and Megasphaera correlated with six metabolic pathways, notably carnitine shuttle and tryptophan metabolism. Interventions that target the underlying microbiome-metabolome pathway may be effective in reducing PNS, including the use of pre- and probiotics, fecal microbiome transplantation, dietary modifications, and increased physical activity. Future multi-omics research is needed to corroborate the associations between the microbiome, metabolome, and PNS outcomes in the pediatric oncology population.

BACKGROUND: The gut microbiome is central to human health, but the potential impact of ozone (O3) exposure on its establishment in early life has not been thoroughly examined. Therefore, this study aimed to investigate the relationship between prenatal O3 exposure and the variations of the human gut microbiome during the first two years of life. DESIGN: A cohort study design was used. Pregnant women in the third trimester were recruited from an obstetric clinic, and long-term follow-ups were conducted after delivery. The gut microbiome was analyzed using the 16â¯S rRNA V3-V4 gene regions. Functional pathway analyses of gut microbial communities in neonates were performed using Tax4fun. The average concentrations of ambient O3 and other air pollutants from pregnancy to delivery were calculated using the China High Air Pollutants (CHAP) dataset, based on the permanent residential addresses of participants. Multiple linear regression and mixed linear models were utilized to investigate the associations between prenatal O3 exposure and gut microbiome features. RESULTS: Prenatal O3 exposure did not significantly affect the gut microbial alpha diversity of mothers and neonates. However, it was found to be positively associated with the gut microbial alpha diversity in 24-month-old infants. Prenatal O3 exposure explained 13.1â¯% of the variation in neonatal gut microbial composition. After controlling for potential covariates, prenatal O3 exposure was associated with neonatal-specific gut microbial taxa and functional pathways. Furthermore, the mixed linear models showed that prenatal O3 exposure was negatively associated with variations of Streptococcus (p-value = 0.001, q-value = 0.005), Enterococcus (p-value = 0.001, q-value = 0.005), Escherichia-Shigella (p-value = 0.010, q-value = 0.025), and Bifidobacterium (p-value = 0.003, q-value = 0.010). CONCLUSIONS: This study is the first to examine the effects of prenatal O3 exposure on gut microbial homeostasis and variations. It demonstrates that prenatal O3 exposure is associated with variations in certain aspects of the gut microbiome. These findings provide novel insights into the dynamics and establishment of the human microbiome during the first two years of life.

The infant gut microbiome matures greatly in the first year of life. Ambient air pollution (AAP) exposure is associated with the infant gut microbiome. However, whether time-varying AAP influences infant gut microbiome variation is rarely investigated. This study aimed to investigate the effects of PM2.5, PM10, and O3 on infant gut microbiome variation longitudinally. Demographic information, stool samples, and AAP exposure concentrations were collected at 6, 12, 24 months from infants. Gut microbiome was processed and analyzed using 16S rRNA V3-V4 gene regions. AAP exposure concentrations were calculated using the China High Air Pollutants (CHAP) database. Multiple pollutant models were used to assess the mixed effects of PM2.5, PM10, and O3 on infant gut microbiome variation. Infants' gut microbiomes at 6, 12, 24 months old had significant differences in alpha diversity, beta diversity, and community composition. PM2.5 and O3 respectively explained 6.3% and 5.3% of the differences in community composition for 24-month-old infants. Single pollutant exposure and multiple pollutant exposure in different periods were both associated with alpha diversity indices and specific gut microbial phyla and genera. AAP was more associated with infant gut microbial alpha diversity indices, phyla variations, and genera variations at 12-24 months than 6-12 months. Multiple pollutant exposure in 0-2 lag months showed negative correlations with 12-24 months variation in Escherichia-Shigella (ß = -0.854, 95%CI: 1.398 to -0.310) and Enterococcus (ß = -0.979, 95%CI: 1.429 to -0.530). This study highlighted that time-varying PM2.5, PM10, and O3 synergistically influenced the variation of alpha diversity and abundance of gut microbial taxa in infants. Further research is needed to explore the effects and mechanisms of other environmental exposures on infant gut microbiome variation.

This review summarizes the relationship between diet, the gut microbiome, and migraine. Key findings reveal that certain dietary factors, such as caffeine and alcohol, can trigger migraine, while nutrients like magnesium and riboflavin may help alleviate migraine symptoms. The gut microbiome, through its influence on neuroinflammation (e.g., vagus nerve and cytokines), gut-brain signaling (e.g., gamma-aminobutyric acid), and metabolic function (e.g., short-chain fatty acids), plays a crucial role in migraine susceptibility. Migraine can also alter eating behaviors, leading to poor nutritional choices and further exacerbating the condition. Individual variability in diet and microbiome composition highlights the need for personalized dietary and prebiotic interventions. Epidemiological and clinical data support the effectiveness of tailored nutritional approaches, such as elimination diets and the inclusion of beneficial nutrients, in managing migraine. More work is needed to confirm the role of prebiotics, probiotics, and potentially fecal microbiome translation in the management of migraine. Future research should focus on large-scale studies to elucidate the underlying mechanisms of bidirectional interaction between diet and migraine and develop evidence-based clinical guidelines. Integrating dietary management, gut health optimization, and lifestyle modifications can potentially offer a holistic approach to reducing migraine frequency and severity, ultimately improving patient outcomes and quality of life.

BACKGROUND: Prenatal psychological distress and maternal inflammation can increase the risk of neurodevelopmental delay in offspring; recently, the gut microbiota has been shown to may be a potential mechanism behind this association and not fully elucidated in population study. METHODS: Seventy-two maternal-infant pairs who completed the assessments of prenatal psychological distress during the third trimester and neurodevelopment of infants at age 6-8 months of age were included in this study. The gut microbiota and its short-chain fatty acids (SCFAs) of maternal-infant were determined by 16S rRNA sequencing and liquid chromatography-mass spectrometry analysis. Inflammatory cytokines in the blood of pregnant women during the third trimester were detected by luminex liquid suspension microarrays. RESULTS: This study found that infants in the prenatal psychological distress group had poorer fine motor skills (ß = -4.396, 95 % confidence interval (CI) = -8.546, -0.246, p = 0.038), problem-solving skills (ß = -5.198, 95 % CI = -10.358, -0.038, p = 0.048) and total development (ß = -22.303, 95%CI = -41.453, -3.153, p = 0.022) compared to the control group. The study also indicated that the higher level of interleukin-1ß (IL-1ß) (ß = -1.951, 95%CI = -3.321, -0.581, p = 0.005) and interferon-inducible protein-10 (IP-10) (ß = -0.019, 95%CI = -0.034, -0.004, p = 0.015) during the third trimester, the poorer fine motor skills in infants. Also, the higher level of IL-10 (ß = -0.498, 95%CI = -0.862, -0.133, p = 0.007), IL-12p70 (ß = -0.113, 95%CI = -0.178, -0.048, p = 0.001), IL-17 A (ß = -0.817, 95%CI = -1.517, -0.118, p = 0.022), interferon-γ (ß = -0.863, 95%CI = -1.304, -0.422, p < 0.001), IP-10 (ß = -0.020, 95%CI = -0.038, -0.001, p = 0.035), and regulated upon activation normal T cell expressed and secreted (ß = -0.002, 95%CI = -0.003, -0.001, p = 0.005) during the third trimester, the poorer problem-solving skills in infants. After controlling for relevant covariates, this study found that maternal gut microbiota Roseburia mediates the relationship between prenatal psychological distress and total neurodevelopment of infants (a = 0.433, 95%CI = 0.079, 0.787, p = 0.017; b = -19.835, 95%CI = -33.877, -5.792, p = 0.006; c = 22.407, 95%CI = -43.207,-1.608, p = 0.035; indirect effect = -8.584, 95%CI = -21.227, -0.587). CONCLUSIONS: This is the first study to emphasize the role of the maternal-infant gut microbiota in prenatal psychological distress and infant neurodevelopment. Further studies are needed to explore the biological mechanisms underlying the relationship between prenatal psychological distress, maternal-infant gut microbiota, and infant neurodevelopment.

INTRODUCTION: Travel burden leads to worse cancer outcomes. Understanding travel burden and the level and types of travel support provided at large cancer centers is critical for developing systematic programs to alleviate travel burden. This study analyzed patients who received travel assistance, including their travel burden, types and amount of travel support received, and factors that influenced these outcomes. METHODS: We analyzed 1063 patients who received travel support from 1/1/2021 to 5/1/2023 at Winship Cancer Institute, in which ~18,000 patients received cancer care annually. Travel burden was measured using distance and time to Winship sites from patients' residential address. Travel support was evaluated using the monetary value of total travel support and type of support received. Patients' sociodemographic and clinical factors were extracted from electronic medical records. Area-level socioeconomic disadvantage was coded by the Area Deprivation Index using patient ZIP codes. RESULTS: On average, patients traveled 57.2 miles and 67.3 min for care and received $74.1 in total for travel support. Most patients (88.3%) received travel-related funds (e.g., gas cards), 5% received direct rides (e.g., Uber), 3.8% received vouchers for taxi or public transportation, and 3% received combined travel support. Male and White had longer travel distance and higher travel time than female and other races, respectively. Patients residing in more disadvantaged neighborhoods had an increased travel distance and travel time. Other races and Hispanics received more travel support ($) than Black and White patients or non-Hispanics. Patients with higher travel distance and travel time were more like to receive travel-related financial support. CONCLUSION: Among patients who received travel support, those from socioeconomically disadvantaged neighborhoods had greater travel burden. Patients with greater travel burden were more likely to receive travel funds versus other types of support. Further understanding of the impact of travel burden and travel support on cancer outcomes is needed.

OBJECTIVE: To profile the gut microbiome (GM) in infants with congenital heart disease (CHD) undergoing cardiac surgery compared with matched infants and to investigate the association with growth (weight, length, and head circumference). STUDY DESIGN: A prospective study in the cardiac intensive care unit at Children's Healthcare of Atlanta and newborn nursery within the Emory Healthcare system. Characteristics including weight, length, head circumference, and surgical variables were collected. Fecal samples were collected presurgery (T1), postsurgery (T2), and before discharge (T3), and once for controls. 16 small ribosomal RNA subunit V4 gene was sequenced from fecal samples and classified into taxonomy using Silva v138. RESULTS: There were 34 children with CHD (cases) and 34 controls. Cases had higher alpha-diversity, and beta-diversity showed significant dissimilarities compared with controls. GM was associated with lower weight and smaller head circumference (z-score < 2). Lower weight was associated with less Acinetobacter, Clostridioides, Parabacteroides, and Escherichia-Shigella. Smaller head circumference with more Veillonella, less Acinetobacter, and less Parabacteroides. CONCLUSIONS: Significant differences in GM diversity and abundance were observed between infants with CHD and control infants. Lower weight and smaller head circumference were associated with distinct GM patterns. Further study is needed to understand the longitudinal effect of microbial dysbiosis on growth in children with CHD.
RÉSUMÉ
The purpose of this study was to explore whether prenatal gut microbiota (GM) and its functions predict the development of offspring temperament. A total of 53 mothers with a 1-year-old child and 41 mothers with a 2-year-old child were included in this study using a mother-infant cohort from central China. Maternal fecal samples collected during the third trimester were analyzed using 16S rRNA V3-V4 gene sequences. Temperament of the child was measured by self-reported data according to the primary caregiver. The effects of GM in mothers on offspring's temperament were evaluated using multiple linear regression models. The results demonstrated that the alpha diversity index Simpson of prenatal GM was positively associated with the activity level of offspring at 1 year (adj. P = .036). Bifidobacterium was positively associated with high-intensity pleasure characteristics of offspring at 1 year (adj. P = .031). Comparatively, the presence of Bifidobacterium found in the prenatal microbiome was associated with low-intensity pleasure characteristics in offspring at 2 years (adj. P = .031). There were many significant associations noted among the functional pathways of prenatal GM and temperament of offspring at 2 years. Our findings support the maternal-fetal GM axis in the setting of fetal-placental development with subsequent postnatal neurocognitive developmental outcomes, and suggest that early childhood temperament is in part associated with specific GM in the prenatal setting.
RÉSUMÉ
The gut microbiome has been reported to be associated with nighttime light (NTL) exposure and temperament. However, the specific role of infant gut microbiome plays in NTL exposure and temperament is unclear. This study investigated the potential mediating role of infants' gut microbiome in correlations between NTL exposure and temperament. Demographic information, stool samples, and temperament scores were collected from 40 infants. Temperament was evaluated using the Infants Behavior Questionnaire-Revised (IBQ-R). The gut microbiota was analyzed using 16S rRNA sequencing. Cumulative and lagged effects of NTL exposure were calculated based on residential address (NTLpoint) and a concentric 1 km radius buffer zone around the address (NTL1000m), respectively. Mediation models were utilized for assessing the mediating effects of the gut microbiome. The gut microbiome of infants with higher fear scores was characterized by a higher abundance of Akkermansia and Clostridium_sensu_stricto_1 and a lower abundance of Bacteroides. Mediation models indicated Akkermansia played a full mediating role in associations between NTLpoint, NTL1000m and fear in specific time periods. Genus Akkermansia explained 24.46% and 33.50% of associations between fear and cumulative exposure to NTLpoint and NTL1000m, respectively. This study provides evidence for the mediating role of Akkermansia between NTL exposure and fear. However, further experimental is required to elucidate the mechanisms through which the gut microbiome mediates between NTL exposure and temperament in infants.

OBJECTIVE: This longitudinal study sought to explore the impact of cortisol and hope levels on Fear of Cancer Recurrence (FCR) and Quality of Life (QOL) in a cohort of 552 breast cancer patients from three centers in Wuhan City. METHOD: A longitudinal study involving 552 breast cancer patients from three centers in Wuhan City utilized Chinese versions of the Fear of Progression Questionnaire-Short Form (FoP-Q-SF), the Herth Hope Index (HHI), and the Functional Assessment of Cancer Therapy-Breast (FACT-B) scale. Cortisol levels were measured thrice daily, and data was collected longitudinally three times. Data analysis was conducted using SPSS 26.0 and Mplus 8.3, employing a longitudinal path model constructed via the cross-lagged method. RESULTS: The results showed there were significant correlations between FCR, cortisol levels, and QOL at different time points. A significant mediating model was found with outcomes related to hope levels. Specifically, FCR predicted a decrease in hope levels (ß = -0.163, p < 0.001), which in turn led to a decrease in overall QOL (ß = -0.078, p < 0.001), with a mediation effect accounting for 10.34%. Although there were correlations between FCR, cortisol levels, and QOL at different time points, further analysis revealed that cortisol levels did not exhibit a mediating effect between the two (95% confidence interval: -0.002 to 0.001). CONCLUSION: This study demonstrated there were significant correlations among FCR, QOL, and hope levels. Considering hope as a crucial mediator between FCR and QOL, potential intervention strategies for optimizing the QOL of breast cancer patients are proposed.

BACKGROUND: PM2.5 and its chemical components increase health risks and are associated with depression and gut microbiota. However, there is still limited evidence on whether gut microbiota and short-chain fatty acids (SCFAs) mediate the association between PM2.5, PM2.5 chemical components, and antenatal depression. The purpose of this study was to investigate the mediating role of maternal gut microbiota in correlations between short-term exposure to PM2.5, short-term exposure to PM2.5 chemical components, and antenatal depression. METHODS: Demographic information and stool samples were collected from 75 pregnant women in their third trimester. Their exposure to PM2.5 and PM2.5 chemical components was measured. Participants were divided into the non-antenatal depression group or the antenatal depression group according to the cut-off of 10 points on the Edinburgh Postnatal Depression Scale (EPDS). The gut microbiota were analyzed using the 16â¯S rRNA-V3/V4 gene sequence, and the concentration of PM2.5 and its chemical components was calculated using the Tracking Air Pollution in China (TAP) database. Gas chromatography-mass spectrometry was used to analyze SCFAs in stool samples. In order to assess the mediating effects of gut microbiota and SCFAs, mediation models were utilized. RESULTS: There were significant differences between gut microbial composition and SCFAs concentrations between the non-antenatal depression group and the antenatal depression group. PM2.5 and its chemical components were positively associated with EPDS scores and negatively associated with genera Enterococcus and Enterobacter. Genera Candidatus_Soleaferrea (ß = -7.21, 95%CI -11.00 to -3.43, q = 0.01) and Enterococcus (ß = -2.37, 95%CI -3.87 to -0.87, q = 0.02) were negatively associated with EPDS scores, indicating their potential protective effects against antenatal depression. There was no significant association between SCFAs and EPDS scores. The mediating role of Enterococcus between different lagged periods of PM2.5, PM2.5 chemical component exposure, and antenatal depression was revealed. For instance, Enterococcus explained 29.23% (95%CI 2.16-87.13%, p = 0.04) of associations between PM2.5 exposure level at the day of sampling (lag 0) and EPDS scores. CONCLUSION: Our study highlights that Enterococcus may mediate the associations between PM2.5, PM2.5 chemical components, and antenatal depression. The mediating mechanism through which the gut microbiota influences PM2.5-induced depression in pregnant women still needs to be further studied.

BACKGROUND: Children with cancer receiving chemotherapy commonly report a cluster of psychoneurological symptoms (PNS), including pain, fatigue, anxiety, depression, and cognitive dysfunction. The role of the gut microbiome and its functional metabolites in PNS is rarely studied among children with cancer. This study investigated the associations between the gut microbiome-metabolome pathways and PNS in children with cancer across chemotherapy as compared to healthy children. METHODS: A case-control study was conducted. Cancer cases were recruited from Children's Healthcare of Atlanta and healthy controls were recruited via flyers. Participants reported PNS using the Pediatric Patient-Reported Outcomes Measurement Information System. Data for cases were collected pre-cycle two chemotherapy (T0) and post-chemotherapy (T1), whereas data for healthy controls were collected once. Gut microbiome and its metabolites were measured using fecal specimens. Gut microbiome profiling was performed using 16S rRNA V4 sequencing, and metabolome was performed using an untargeted liquid chromatography-mass spectrometry approach. A multi-omics network integration program analyzed microbiome-metabolome pathways of PNS. RESULTS: Cases (n = 21) and controls (n = 14) had mean ages of 13.2 and 13.1 years. For cases at T0, PNS were significantly associated with microbial genera (e.g., Ruminococcus, Megasphaera, and Prevotella), which were linked with carnitine shuttle (p = 0.0003), fatty acid metabolism (p = 0.001) and activation (p = 0.001), and tryptophan metabolism (p = 0.008). Megasphaera, clustered with aspartate and asparagine metabolism (p = 0.034), carnitine shuttle (p = 0.002), and tryptophan (p = 0.019), was associated with PNS for cases at T1. Gut bacteria with potential probiotic functions, along with fatty acid metabolism, tryptophan, and carnitine shuttle, were more clustered in cancer cases than the control network and this linkage with PNS needs further studies. CONCLUSIONS: Using multi-omics approaches, this study indicated specific microbiome-metabolome pathways linked with PNS in children with cancer across chemotherapy. Due to limitations such as antibiotic use in cancer cases, these findings need to be further confirmed in a larger cohort.

Background Microbiome studies in humans, though limited, have facilitated the evaluation of the potential connection between the microbiome and brain function. Children with autism spectrum disorder (ASD) have several behavioral challenges and avoidant/restrictive food intake disorder, which may contribute to gut microbiome dysbiosis. Aim The aim of this study is to examine the extent to which the gut microbiome of children with ASD differs in comparison to children with neurotypical development (CWND) and to assess whether a probiotic intervention has the potential to influence the gut microbiome in mediating positive behavior change and stress regulation. Methods This pilot study collected data from three children with ASD and four CWND before and after a four-week probiotic intervention. Data collection included microbiome diversity screening from stool samples as well as the following biophysiological measures: salivary alpha-amylase (sAA) levels, response to simulated stressor and calming stimulus (behavior), including pulse rate, galvanic skin response, and pupil diameter (PD). In addition, telomere length was assessed. All measures, except for telomere length, were repeated after the four-week intervention on the ASD and CWND groups for pre-/post-comparison. Data analysis consisted of multivariate analyses, including ANOVA. Results While greater heterogeneity in the ASD group was evident in all measures, the gut microbiome of participants who received probiotic intervention differed from pretreatment results within and across the groups investigated. Further, the biophysiological parameter sAA displayed a significant increase between baseline and exposure to stress in both groups, whereas PD increased in both groups from baseline, F(11, 26615) = 123.43, p = 0.00. Conclusion Though gut microbiome diversity is diminished in children with ASD compared to CWND, the gap is narrowed following a brief probiotic intervention. The results suggest that probiotic interventions have the potential to rescue microbiome diversity and abundance, potentially supporting stress regulation in pediatric populations.
RÉSUMÉ
Many studies have focused on the effect of perinatal depression on neurodevelopment among children and adolescents. However, only a few studies have explored this relationship in infants and toddlers with inconsistent results. We performed a systematic review and meta-analysis to evaluate the association between perinatal depression and infant and toddler neurodevelopment during the first two postnatal years. Twenty-three studies were included in this meta-analysis. Perinatal depression was associated with poorer cognitive (Cohen's d = -0.19, SE= 0.06, 95% CI = -0.30 to -0.08), language (Cohen's d = -0.24, SE = 0.09, 95% CI = -0.40 to -0.07), and motor (Cohen's d = -0.15, SE = 0.05, 95% CI = -0.26 to -0.05) development. Subgroup analyses showed that the types of maternal depression (prenatal depression vs. postnatal depression), the method of measuring maternal depression (rating scale vs. diagnostic interview), and the time interval between assessment of exposure and outcome had an impact on the observed effect about neurodevelopment of infants and toddlers. In addition, the results of our study pointed to a stronger significant association between prenatal depression and cognitive, language, and motor delays in infants and toddlers, whereas the association between postnatal depression and cognitive, language, and motor delays in infants and toddlers was not statistically significant. In conclusion, this study provided convincing evidence that the perinatal window is a sensitive period for offspring neurodevelopment.

AIM: The number of breast cancer patients is increasing, but there are insufficient sources of information for their family caregivers. The purpose of this systematic review was to elaborate the psychologically realistic experiences and corresponding needs of family members of patients with breast cancer in the course of their experience in the disease which may provide them with effective, targeted intervention strategies to improve their quality of life. DESIGN: Protocol for a meta-synthesis. METHODS: We will search the Chinese databases (i.e., China National Knowledge Infrastructure, VIP Database and Wanfang Database) and the English databases (i.e., PubMed, Embase, Web of Science, the Cochrane Library, CINAHL and PsycINFO). Qualitative studies from the above databases, studying the psychological experiences of family members of patients with breast cancer, will be searched comprehensively. The quality of the study will be evaluated by two reviewers independently using the Joanna Briggs Institute (JBI) critical appraisal tools for qualitative study, and any disagreements will be discussed and judged by the third reviewer. Data will be extracted using JBI standardized data extraction tool. Then, the literature will be compared and analysed, and the raw results summarized using the JBI meta-aggregation tool. The reliability and credibility of the overall quality of the included studies will be assessed by using the JBI ConQual approach. RESULTS: N/A. No Patient or Public Contribution. PROSPERO REGISTRATION NUMBER: REDACTED.

CONTEXT: The community structure of gut microbiota changes during pregnancy, which also affects the synthesis of short-chain fatty acids (SCFAs). However, the distribution of gut microbiota composition and metabolite SCFA levels are poorly understood in women undergoing assisted reproductive technology (ART). AIMS: To evaluate the changes in gut microbiota composition and metabolic SCFAs in women who received assisted reproduction treatment. METHODS: Sixty-three pregnant women with spontaneous pregnancy (SP) and nine with ART pregnancy were recruited to provide fecal samples. Gut microbiota abundance and SCFA levels were determined by 16S ribosomal RNA (rRNA) gene amplicon sequencing and gas chromatography-mass spectrometry (GC-MS). KEY RESULTS: The ART group showed decreased alpha diversity (the species richness or evenness in a sample). The principal coordinates analysis (a method of analysing beta diversity) showed significant difference in gut microbiota between the ART group versus the SP group (unweighted UniFrac distance, R 2 =0.04, P =0.003). Proteobacteria , Blautia and Escherichia-Shigella were enriched in the ART group, whereas the relative abundance of beneficial intestinal bacteria Faecalibacterium was lower than in the SP group. Different modes of conception were associated with several SCFAs (valeric acid (r =-0.280; P =0.017); isocaproic acid (r =-0.330; P =0.005); caproic acid (r =-0.336; P =0.004)). Significantly different SCFAs between the two groups were synchronously associated with the differential gut microbiota. CONCLUSIONS: The diversity and abundance of gut microbiota and the levels of SCFAs in women undergoing ART decreased. IMPLICATIONS: The application of ART shaped the microbial composition and metabolism, which may provide critical information for understanding the biological changes that occur in women with assisted reproduction.

AIMS: To investigate the impact of pregnancy with combined hepatitis B virus (HBV) infection and Gestational diabetes mellitus (GDM) on fetal growth and adverse perinatal outcomes. METHODS: All the pregnant women with HBV infection and/or GDM who delivered at Women's Hospital, Zhejiang University between January 2015, and September 2022 were included. A total of 1633 pregnant women were recruited in the final analysis, including 409 women with HBV infection and GDM, 396 with HBV infection only, 430 with GDM only, and 398 without HBV infection and GDM. Linear and logistic regression models were used to study the impact of pregnancy with combined HBV infection and GDM on fetal growth and adverse perinatal outcomes. RESULTS: Pregnancy with combined HBV infection and GDM was associated with increased Z-scores on primary fetal ultrasound parameters and significantly increased the risk of fetal femur length overgrowth (OR: 2.88, 95 % CI: 1.13 â¼ 7.35), placental abruption (OR: 3.64, 95 % CI: 1.18 â¼ 11.22), and macrosomia (OR: 4.19, 95 % CI: 1.66 â¼ 10.56) compared to pregnancy without HBV infection and GDM. CONCLUSIONS: Both maternal HBV infection and GDM are independently associated with adverse perinatal outcomes. Their combination further increases the risk of adverse perinatal outcomes.

OBJECTIVE: To explore the levels and predictors of body image dissatisfaction among women at different stages of pregnancy. DESIGN: This was a cross-sectional study design. SETTING AND PARTICIPANTS: A total of 863 Chinese pregnant women were recruited from a tertiary hospital via a convenience sampling method. MEASUREMENT AND FINDINGS: Eligible participants completed a demographic questionnaire and self-reported measures of body image dissatisfaction, pregnancy-related anxiety, prenatal depression, and appearance comparison. Results showed no statistical difference in body image dissatisfaction levels among early-mid pregnancy (47.6 ± 6.17), late-mid pregnancy (47.3 ± 7.56), and late pregnancy stages (48.4 ± 6.22). The generalized linear model showed that gestational weight gain, pregnancy-related anxiety, own/family's perception of pregnancy weight, and current ideal weight change were predictors of body image dissatisfaction in the early-mid pregnancy stage. In addition, pre-pregnancy BMI, appearance comparison, own /family's perception of pregnancy weight, current ideal weight change, and overeating during pregnancy significantly predicted body image dissatisfaction in the late-mid pregnancy stage. Predictors of body image dissatisfaction in the late pregnancy stage comprised planned pregnancy, pre-pregnancy eating disorders, own perception of pregnancy weight, current ideal weight change, pregnancy-related anxiety, and prenatal depression. KEY CONCLUSION AND IMPLICATION FOR PRACTICE: The findings suggest that predictors of body image dissatisfaction differed according to pregnancy stage. Self-perception of pregnancy weight was primary predictor of body image dissatisfaction. Healthcare professionals are recommended to provide prenatal health education to reduce own/family's negative perception of pregnancy weight, so as to alleviate the body image dissatisfaction level of pregnant women.

ABSTRACT: Chronic pain is a primary health problem in people living with HIV (PWH). However, there is limited research regarding chronic pain among PWH in Chinese health care settings. To investigate biopsychosocial factors of chronic pain severity, we conducted a cross-sectional study in Shenzhen, China. Chronic pain was defined as pain lasting for more than three months. Pain intensity was measured using the numeric rating scale (NRS). Among 123 hospitalized PWH, 78.86% of participants had mild pain and 21.14% had moderate-severe pain. Multiple logistic regression results indicated that PWH in moderate-severe pain group were more likely to have higher levels of interleukin [IL]-6 (OR = 1.034, 95% CI: 1.003-1.066, p = .029) and anxiety (OR = 1.334, 95% CI: 1.071-1.662, p = .010) than those in the mild chronic pain group. Targeted pain management interventions should be explored in clinical practices and future studies regarding PWH with high levels of IL-6 and anxiety.
